Job Description

Not Your Typical Engineering Role

This isn’t about shipping features for the sake of it. This is about shaping how AI powers a platform used by over a million people globally systems that are operationally serious, ethically guided, and scaling fast.

You’ll work alongside a team of ~40 world-class engineers, recently strengthened by senior talent from top-performing product and scale-up environments. The technical bar has never been higher, and the culture is defined by:

• Technical excellence

• Clear system design thinking

• High ownership and accountability

• Fast iteration and calibration

• Customer-first decision making

You’ll report to a senior engineering leader who also oversees AI and platform strategy. Expect real architectural discussions, not surface-level decisions.

The company is now AI-first, investing heavily in responsible, human-guided AI to tackle real-world, non-clinical health and safety challenges. And this is just the beginning, the AI layer is becoming core to the platform experience.

The Problem You’ll Own

The platform is at a pivotal point:

• Two fully scaled systems, front-end and back-end, need to evolve together without slowing down.

• AI-driven services, from predictive triage to intelligent automation are now central to how the platform delivers impact.

• Every architectural choice you make today will shape how millions of people get help tomorrow.

The Work You’ll Lead

• Build and scale features across front-end and back-end, integrating AI thoughtfully.

• Prototype, experiment, and ship AI/ML capabilities that genuinely improve outcomes.

• Influence system design and architecture for reliability, performance, and scale.

• Mentor peers and elevate engineering standards across the team.

• Extra credibility: showcasing outside projects, open-source contributions, or personal AI work is highly regarded.

The Profile That Excels

• 4+ years full-stack experience (React/Angular/Vue + Node.js/Python/Java)

• Hands-on AI/ML experience (TensorFlow, PyTorch, OpenAI, Hugging Face, LangChain)

• Cloud-native expertise (AWS/GCP/Azure) and modern CI/CD practices

• Comfortable designing scalable APIs (REST/GraphQL) and distributed systems

• Thrives in high-bar, high-accountability environments

Why This Role Stands Out

• You see the real impact of your work on people’s lives.

• You’ll get architectural ownership over a platform at global scale.

• You’ll collaborate with engineers from top product-led companies.

• Flexible hybrid work, ESOP, wellbeing support, and study leave.

This role isn’t about tickets. It’s for engineers who want to own the technical direction of AI in a high-impact platform. If that’s you, let’s talk, the next three to five years of your career could be defined here.
